Just a perfect day. Indian summer. The bees bring in pollen in abundancy. I just discovered the immense ivy covering the whole wall of la Bellone. Winterfood for my bees.
Today I started to note down the inside hive t° every hour, and compared it to the outside t° and the outside humidity.
In the sun, reading Indeterminacy. Cage was a well-known mycologist. Crazy about fungi. Short stories and mesostics about mushrooms. And later in the afternoon I met Thoreau. Walden & the civil disobedience. Wild is exiting, he says. And tame is dull.
Writing the wilderness. Can a poem give expression to nature?
Later, before sunset, cleaned out the rotten tomatoes but took their seeds for next year… and sown some winter lettuce in the cold greenhouse. The olives are slowly ripening and the figues are big and sweet.

The day and night of 2010/10/10 I did some measurements inside and outside hive#01. On the document you can see that the in- and outside t° are running up- and down on a proportional basis.
The t° sensor was placed at the outer inside of the hive, not in the broodnest itself. On saturday, october 16th, I expanded the observation by adding a digital thermometer to the hive#03, which is situated next to hive#01. I put the sensor in both hives in the broodnest itself. The average outside t° is much colder yet, at night the t° often falls down towards 4°.
I noticed the immediate rise of inside-hive t°, now that the sensor is in the center of the broodnest.
In daytime (no immediate sun) the hive t° was rising till 36°, at night the t° fell down to 23°. There is a difference of ± 3° in the average inside hive t° of hive#01 (less) and hive@02 (more). I don’t know (but should find out) if this t° difference is due to the (still) high varroa contamination of hive#01, even after 2 treatments with Thymovar.

p.s.
The drawing on the rooftop is part of an art project by GOeART.

Following the Nazca lines, let’s turn the roofs of buildings and unused, abandoned spaces into works of art that can be seen from space! This is not just about being creative and artistic, but also making gestures on invisible, unknown and unused areas of our heritage. Being able to access aerial views of these areas is an unprecedented opportunity to practice a monumental art which says something about us, where we live or don’t live, how we relate to a globalised world, our intimacies, these holes, these windows which hide and reveal us … How? Let’s use the roofs of our city as something to draw on. You can’t see these drawings from terra firma, only from the sky. New works can be seen each time the satellites that take aerial views of our cities and areas pass overhead. Find our hidden guides, get up on the roofs and help create the first work of art visible from space.
